But if you really want to max out Performance Lab SPORT Fat Burner results, you must work out — with bonus fat-loss benefits for fasted training. Let’s see how this formula may produce impressive lean body composition results in this review.

About Performance Lab SPORT Fat Burner

Performance Lab SPORT Fat Burner is a sports nutrition formula in Opti-Nutra’s new line of supplements for human performance optimization. Formula notes:

Suggested Use: For best results, take 2-4 capsules 15 minutes prior to training. Performance Lab® Sport Fat Burner is designed to be taken in conjunction with a sensible diet and regular exercise program.

Performance Lab SPORT Fat Burner innovates weight loss supplementation by enhancing both fat-burning and muscle-building in many different ways.

Performance Lab SPORT Fat Burner reflects the science-driven approach that we see in other Performance Lab formulas. SPORT Fat Burner:

Supplies just four ingredients, enabling effective dosing across the board

And, like other Performance Lab products, Performance Lab SPORT Fat Burner addresses a popular supplement category in a fresh way – using new research and some new stacking strategies. The ingredients:

HMB (ß-Hydroxy ß-Methylbutyrate), 1000 mg

The problem: During fasting, the body not only burns through fat stores, but also breaks downmuscle. This is a shame because fasted training and lean muscle mass are both great for fat loss.

Enter HMB, which is featured in Performance Lab SPORT Fat Burner because it has been shown to help protect and preserve lean muscle mass during fasting training. Instead HMB helps the body to use energy stored in fat as a primary fuel source for intense workouts.

HMB is a single ingredient that might just be the perfect sports nutrient for losing fat and gaining lean muscle – which in turn sets up a great metabolic state for continuing to lose weight and keeping it off.

Coleus Forskohlii (Forslean®, 10% forskolin), 250 mg

Coleus Forskohlii is another ingredient, like HMB, that has pro-muscle/anti-fat benefits. But Coleus Forskohlii gets there using separate pathways from HMB, making it a nice complement.

Coleus Forskohlii instead works by regulating cyclic adenosine monophosphate (cAMP), a signaling molecule that plays a role in:

Cayenne Pepper (Capsimax®, 2% capsaicinoids), 50 mg

Cayenne pepper is a great metabolic nutrient for weight loss. It may work by boosting hormones that regulate thermogenesis, a raising of cells energy expenditure that boosts body heat and increases the number of calories burned for any given exercise.

Ultimately, we see Performance Lab SPORT Fat Burner as a versatile formula for building (and preserving) lean muscle mass while accelerating fat loss.

More lean muscle and less body fat is the body composition for healthy metabolism and better exercise performance — so, in theory, fat loss with Performance Lab SPORT Fat Burner might get easier and easier over time.

Who Takes It?

Anyone can take Performance Lab SPORT Fat Burner, but it’s designed for people who exercise while dieting, and will achieve the best body composition results in people who are working out.
